Embodiment 1
[0013] a. Take 50-60% of graphite tailings, 10-20% of shale, and 15-25% of slag according to the mass percentage. After being crushed by a crusher, mix evenly, then add 5-10% of the above-mentioned total mass of water, and stir evenly ;
[0014] b. Put the stirred mixture into a mould, press and form it under a pressure of 20-50 MPa to obtain adobe, and dry it;
[0015] c. Put the dried bricks into a self-ignition brick kiln, and use the heat generated by the spontaneous combustion of combustible solid waste to realize the firing of ceramic ecological bricks. After cooling out of the kiln, solid waste ceramic ecological bricks are obtained.
Embodiment 2
[0017] a. Take 40-50% of graphite tailings, 20-30% of shale, and 15-25% of coal gangue according to the mass percentage, after being crushed by a crusher, mix evenly, then add 10-20% of the above-mentioned total mass of water, and stir Uniform;
[0018] b, putting the stirred mixture into an extrusion molding machine, extruding to obtain brick adobe, and drying;
[0019] c. Put the dried bricks into a self-ignition brick kiln, and use the heat generated by the spontaneous combustion of combustible solid waste to realize the firing of ceramic ecological bricks. After cooling out of the kiln, solid waste ceramic ecological bricks are obtained.
Embodiment 3
[0021] a. Take 50-60% of graphite tailings, 10-20% of shale, 10-20% of coal gangue, and 5-10% of slag according to mass percentage. 20% moisture, stir evenly;
[0022] b, putting the stirred mixture into an extrusion molding machine, extruding to obtain brick adobe, and drying;
[0023] c. Put the dried bricks into a self-ignition brick kiln, and use the heat generated by the spontaneous combustion of combustible solid waste to realize the firing of ceramic ecological bricks. After cooling out of the kiln, solid waste ceramic ecological bricks are obtained.

Abstract
The invention relates to a ceramic ecological brick produced by solid waste, and belongs to the solid waste utilizing and new material field. The product is made by using the graphite gangue as the main material and adding wedding agent with a certain rate and utilizes the heat energy generated by the burning of the flammable solid waste to realize the burning of the products. The invention solves the pollution problems of the solid waste and reduces the cost of the ceramic ecological brick by utilizing the solid waste to produce the ceramic ecological brick. The solid waste ceramic ecological brick has good permeability of water and can prevent the road seeper and improve the growth of the ground surface plant. With good moisture retention, the invention is useful for adjusting the temperature and the humidity of the city ground surface, reducing the thermal conductance and having significant meaning to the adjustment of the city atmosphere, the protection of the underground water material and the city environment.
Description
technical field [0001] The invention relates to a ceramic ecological brick made from solid waste, which belongs to the field of solid waste utilization and new materials. Background technique [0002] With the acceleration of urban construction, the urban surface is gradually covered by buildings and road hardening materials such as concrete, granite, and ceramic tiles. While this brings convenience to people's travel, it also brings negative effects. These pavement hardening materials are air-tight and water-tight materials. After the pavement is hardened, natural precipitation cannot penetrate into the ground, affecting the growth of surface plants; the so-called "heat island effect" is produced, which deteriorates the urban ecological environment; at the same time, it also destroys the natural water cycle and wastes the increasingly scarce natural fresh water resources. [0003] In order to solve the above problems, ceramic permeable bricks with water permeable function ...
